Nomenclature

The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

  • TRICHOMYRMEX [Myrmicinae: Crematogastrini]
    • Trichomyrmex Mayr, 1865: 19. Type-species: Trichomyrmex rogeri, by monotypy.
    • Trichomyrmex junior synonym of Monomorium: Ettershank, 1966: 82; Bolton, 1987: 296.
    • Trichomyrmex revived from synonymy of Monomorium: Ward et al., 2014: 16.
  • EQUESTRIMESSOR [junior synonym of Trichomyrmex]
    • Equestrimessor Santschi, 1919d: 92 [as subgenus of Monomorium]. Type-species: Holcomyrmex chobauti, by subsequent designation of Donisthorpe, 1943f: 644.
    • Equestrimessor junior synonym of Monomorium: Ettershank, 1966: 82; see also discussion in Bolton, 1987: 297.
    • [Ward et al. (2014) transferred the type species of Equestrimessor to Trichomyrmex but did not formally synonimise Equestrimessor under Trichomyrmex although this was implied.]
  • EQUESSIMESSOR [unavailable name]
    • Equessimessor Santschi, 1936a: 32, incorrect subsequent spelling of Equestrimessor.
  • HOLCOMYRMEX [junior synonym of Trichomyrmex]
    • Holcomyrmex Mayr, 1879: 671. Type-species: Holcomyrmex scabriceps, by subsequent designation of Bingham, 1903: 280.
    • [Holcomyrmex Smith, F. 1873: ix. Nomen nudum, attributed to Mayr.]
    • Holcomyrmex junior synonym of Monomorium: Emery, 1908h: 667.
    • Holcomyrmex revived from synonymy as subgenus of Monomorium: Emery, 1915i: 190.
    • Holcomyrmex junior synonym of Monomorium: Ettershank, 1966: 82; see also discussion in Bolton, 1987: 295.
    • Holcomyrmex junior synonym of Trichomyrmex: Ward et al., 2014: 16.
  • PARHOLCOMYRMEX [junior synonym of Trichomyrmex]
    • Parholcomyrmex Emery, 1915i: 190 [as subgenus of Monomorium]. Type-species: Myrmica gracillima (junior synonym of Atta destructor), by original designation.
    • Parholcomyrmex junior synonym of Monomorium: Ettershank, 1966: 82; Bolton, 1987: 296.
    • Parholcomyrmex junior synonym of Trichomyrmex: Ward et al., 2014: 16.
  • [Paraholcomyrmex Emery, 1915i: 191; Forel, 1917: 242; incorrect subsequent spellings.]
